The sco_pmd daemon implements the license policy manager.
When you execute SCO software that requires a license to run,
the sco_pmd daemon checks with the PMD
to verify that the software is correctly licensed.
If not, sco_pmd applies a ``policy decision''
to determine if the software is allowed to continue running.
Certain applications make further internal policy decisions
based on the decision made by the PMD.
sco_pmd is started during system initialization
by an entry in the /etc/inittab file,
and should never be stopped.
If the PMD stops running for any reason,
the kernel issues warning messages at an
increasingly frequent rate.
In SCO OpenServer Release 5.0.7, all previous license daemons
are now included in the PMD
within a single daemon process.
The ifor_pmd, ifor_sld, and sco_cpd daemons
used in previous releases no longer exist.
The sco_pmd daemon only requires that a single
process be running, unlike previous SCO OpenServer releases,
where the PMD also spawned a ``watcher'' process.
sco_pmd accepts the following command line options:
Specifies an alternate location
for the /usr/lib/netls/conf/nodelock file.
This option is rarely used, and usually only when instructed to by
Technical Support personnel.
Specifies an alternate location
for the license defaults database,
This file contains license attributes, and is used
by the PMD and
when capturing licenses.
Update the in-kernel license tables. If you manually capture
executing sco_pmd -k informs the kernel
of any new kernel-specific licenses.
This option does not affect licenses for other software.
The PMD updates the kernel tables
automatically once a day.
Refresh the PMD-managed license tables for all applications,
including kernel licenses. This option should be used if you ever
manually add or remove licenses using
List the internal PMD state
and produce diagnostic information on the stdout file.
This list can be fairly long, so piping the
output through the pager is recommended.
This is primarily a diagnostic tool for Technical Support personnel.
However, this option lists all of the licenses currently in use,
which can be useful information for
system administrators to gauge license usage.
Perform an orderly shutdown of the PMD.
Run in the foreground.
By default, the PMD runs in the background.
Use this option to force it to remain in the foreground.
If none of the -k, -r or -l options
are specified, the PMD attempts to start,
either in the background (by default) or in the foreground
if the -f option is specified.
Only one copy of the PMD can run at the same time;
a warning message displays if you attempt to
run more than one copy.
The PMD is a vital system process,
and should never be stopped
unless your intention is to restart it immediately.
Although it is possible to use the
command to stop the PMD,
the preferred mechanism is to use the -s option.
As soon as possible after shutting down the PMD,
it should be started again.
Simply run /etc/sco_pmd with no arguments
to start the daemon in the background.
If the PMD is shut down and restarted,
the kernel issues a warning message,
and the PMD itself displays a more verbose warning
message letting the system administrator know that there may be a
serious system problem.
If the PMD fails to start during system initialization,
the system is unlicensed, and will behave unpredictably.
In this situation, contact your Technical Support
Do not edit or tamper with the sco_pmd binary
in any way. Doing so will render it useless, and the system
will be unlicensed. Only official SCO patches can
update the PMD.
